Detailed Description

An FSA implementation of a FU resource conflict detector.

Definition at line 54 of file ResourceVectorFUResourceConflictDetector.hh.

Constructor & Destructor Documentation

ResourceVectorFUResourceConflictDetector()

ResourceVectorFUResourceConflictDetector::ResourceVectorFUResourceConflictDetector

(

const TTAMachine::FunctionUnit &

fu

)

Constructor.

Parameters

fu	The function unit to detect conflicts for.

Exceptions

InvalidData

If the model could not be built from the given FU.

Member Function Documentation

advanceCycle()

bool ResourceVectorFUResourceConflictDetector::advanceCycle ( )

virtual

Simulates a cycle advance and reports a conflict if detected.

Returns

False in case a conflict is detected, otherwise true.

Reimplemented from FUResourceConflictDetector.

Definition at line 80 of file ResourceVectorFUResourceConflictDetector.cc.

                                                       {
 
    compositeVector_.shiftLeft();
    return true;
}

References compositeVector_, and TTAMachine::ResourceVector::shiftLeft().

Here is the call graph for this function:

issueOperation()

bool ResourceVectorFUResourceConflictDetector::issueOperation ( OperationID  id )

virtual

Issues an operation and reports a conflict if detected.

Parameters

id	The id of the operation to issue.

Returns

False in case a conflict is detected, otherwise true.

Reimplemented from FUResourceConflictDetector.

Definition at line 64 of file ResourceVectorFUResourceConflictDetector.cc.

                                                                       {
 
    const TTAMachine::ResourceVector& operationVector =
        vectors_.resourceVector(id);
    if (compositeVector_.conflictsWith(operationVector, 1))
        return false;
    compositeVector_.mergeWith(operationVector, 1);
    return true;
}

References compositeVector_, TTAMachine::ResourceVector::conflictsWith(), TTAMachine::ResourceVector::mergeWith(), TTAMachine::ResourceVectorSet::resourceVector(), and vectors_.

Here is the call graph for this function:

operationID()

ResourceVectorFUResourceConflictDetector::OperationID ResourceVectorFUResourceConflictDetector::operationID ( const TCEString &  operationName ) const

virtual

Returns an operation id for the given operation.

Operation IDs are used in the interface for optimizing the access. This method converts OSAL Operations to operation IDs.

Parameters

operation

The OSAL Operation to find ID for.

Returns

The operation ID.

Reimplemented from FUResourceConflictDetector.

Definition at line 96 of file ResourceVectorFUResourceConflictDetector.cc.

                                          {
 
    return vectors_.operationIndex(StringTools::stringToUpper(operationName));
}

References TTAMachine::ResourceVectorSet::operationIndex(), StringTools::stringToUpper(), and vectors_.

Here is the call graph for this function:

reset()

void ResourceVectorFUResourceConflictDetector::reset ( )

virtual

Sets the state of the detector to its initial state.

This means that the FU state is assumed to be what it is in powerup.

Reimplemented from FUResourceConflictDetector.
